DINNER-PAIL.

Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed. June 18, 1906. Serial No. 322,322.

To all whom it may concern:

Be it known that I, HENRY W. RYDING, a citizen of the United States,residing at Falun, in the county of Saline and State of Kansas, haveinvented certain new and use ful Improvements in Dinner-Pails, of whichthe following is a specification, reference being had therein to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a vertical longitudinal sectional view of my improved dinnerpail, and on the broken line of Fig. 2. Fig. 2 is a vertical transversesectional view at right angles to the view in Fig. l and on the brokenline of that figure. Fig. 3 is a full view of the improvement asdescribed in this specification.

Similar letters refer to similar parts.

My invention refers to improvements in dinner pails or vessels of likecharacter adapted to contain food; and it has for its objects to providefor the heating of coffee or other liquid and to impart a comfortableand appetizing warmth to the balance of the food contained in the pail,by means of a specially-constructed arrangement adapted to accomplishthe desired results.

Referring to the drawings, A is the pail, J are the ears to which thebail is attached, I is the bail, and L is the handle; P is a tray placedin the body of the pail, A, in the usual way; i is a lid covering thetray, P.

I Gr is a tube or hollow cylinder with the lower end extending throughand to a suit-.

able distance below the lie 2', and to which it is permanently secured.It is provided with a bottom, R, forming the retainer E in the upper endand part of the heating space, D, in the lower end, and below the bottomR. The bottom R is placed, in the cylinder, far enough above the upperside of the lid, 2', to give sufficient room, between the lid anditself, for valves O and slide N (see Fig. 3).

E is the retainer for holding the liquid and is formed by the upper endof cylinder G and the bottom R; it is covered by means of a handleddrinking cup, F When the coflee is being heated, however, the cup isremoved and placed bottom side down over the retainer, E; or the cup maybe left loosely hanging in its inverted position over retainer E so asto allow the developing steam to escape, which is necessary.

F is a cup provided with a handle and is used to cover retainer E toprevent the spilling of its contents, and to drink out of.

O are valves in the body of cylinder G, and situated between the bottom,R, and the upper side of the lid, i, to admit the escape of gases andother products of com bustion developed in the heating space, D.

N is an annular slide designed to cover valves 0; it has a perforation,S, which exposes the valves, 0; when not in use and when necessary toextinguish the flame of the heating device, C, the slide, N, is turnedby means of the thumb piece M so that valves 0 become entirely covered.Slide N is also used to regulate the amount of ventilation throughvalves O.

M is a projection on slide N, and by means of which the slide is turnedback and forth over valves O.

B is a removable tray designed to hold the heating device, C; it has aflange, p, with cut-off portions, a, to enable it to pass the support,H, (see Fig. 1). The tray, B is made to fit smoothly over the lower endof cylinder G; when so fitted, it forms the heating space D, whichcontains the heating device, C. NVhen flange p of tray B has passedsupport H, when tray B is being fitted over lower end of cylinder G, thetray is turned so that the uncut portion of flange 2 rests on thesupport, H, thus maintaining the tray in its proper position.

H, as already noted, is a bar or support, secured transversely to theunder side of the lid, 6, in such a way as to leave a sufficient spacebetween it and the lid to receive the flange, p, of tray B, which thistransverse bar is designed to support in its proper position.

In the body of the tray, B, and a suitable distance above the bottom ofit, are valves, 1", to admit air to heating space D, to make combustionpossible.

V is an annular slide designed to cover valves r in tray B, it has aperforation, X, which exposes valves 1. To prevent any odors frompassing into the pail from heating space D, valves 1" should be keptcovered except when the liquid in retainer E is being heated.

W is a thumb piece attached to slide V and by means of which the slideis turned.

D is the heating space in which the heating device, G, is located and isformed by fitting tray B over the lower end of; cylinder G.

Z are valves in the upper side of the body of the tray, P, to admit air,through valves 1" in tray B, to heating space D, to make combustionpossible. These valves, Z, (see Fig. 2), are covered and uncovered bymeans of a. slide, T. When the liquid in retainer E is not being heated,these valves should be kept covered.

The tray, B, should be so placed, when in position, that the valves, r,in it, are directly opposite to the valves, Z, in the body of the trayP, to allow the air to pass freely from the outside of the pail into theheating space, D, to allow of perfect combustion in said space.

C is a device for heating the liquid contained in the retainer, E, andis placed in the tray B. It is composed of a font, for holding keroseneoil, an ordinary lamp burner, and a wick, and, although not shown in thedrawings, it has a cap and an opening through which the font is filled.No chimney is necessary, as the lamp, or device, burns with a clear,smokeless flame without such a device, the heating space itself actingas a chimney.

When ready to heat the liquid in the retainer, E, the lid, 2', isremoved from the tray, P; the tray B is detached from cylinder Gr; thelamp or heating device, C, is lighted and replaced in tray B, which isagain fitted over the lower end of cylinder G; valves O 0, r and Z areopened, and the lid, 2', is again placed in its position covering tray Pas before;

Y or, if desirable, the lid, 71 may be placed transversely over thetray, P.

The heating arrangement is so constructed that the codes or other liquidmay be heated whether the pail is indoors or out of doors, making itvery convenient to all persons who use this class of utensils andprovides for them a warm and appetizing lunch when circumstances compelthem to take their noonday meals away from home, conducing to specialcomforts the year around, and peculiarly so during the colder seasons.It is simple in construction and economical in cost.

The heating arrangement may, of course, be used with various types ofpails or similar vessels, while various modifications and adaptationsmay be made by the skilled mechanic without departing from the scope ofthe following claim.

WVhat I claim is- In a dinner pail, a lid having a cylinder providedwith a bottom, valves in said cylinder to allow the escape of gases andprod nets of combustion, an annular slide to open and close said valves,a detachable tray fitted over the lower end of said cylinder, valves insaid tray to admit of ventilation, an annular slide to cover and uncoversaid valves, a stay to support said tray in position, a heating devicein said tray, valves in the body of the pail to afford ventilation, anda slide tov cover and uncover said valves.
